Kim Kardashian slams Caitlyn Jenner for comments about late father Robert

A full season later,Caitlyn Jenner‘s memoir is stillstirring up tensionon Keeping Up with the Kardashians.

In a sneak peek at Sunday’s season 14 premiere,Kimand Kourtney Kardashiantravel to Cleveland to visitKhloé Kardashian, who spends much of time there with her boyfriend, Cavaliers playerTristan Thompson — but they’re interrupted by a news alert about Caitlyn’s then-unreleased memoir, The Secrets of My Life.

“It says in Caitlyn’s book Robert Kardashian knew O.J. Simpson wasguilty,but joined the defense team to get back at his re-married ex,” reads Kim, 36. “Robert told Caitlyn in secret after the O.J. murder trial that he believed his friend was guilty.”

“Dadsobelieved in him,” Kim says. “It is so shady that Caitlyn came over and gave me the book, and then on thephoneshe said, ‘Well, the final version has a few more things in it, but don’t worry, it’s nothing about you.’ So she lied to me, because that is aboutme,if it’s aboutourdad.”

“I have always had Caitlyn’s back,” she tells her sisters. “But she is a liar. She is not a good person.”

Caitlyn, 67, wrote that she was in the car with Robert in the late ’90s — following Simpson’s initial acquittal and later conviction of manslaughter in a civil trial — when he allegedly said, “I would’ve been okay with it if they had gotten him in the first trial.”

“The implication was obvious that [Robert] believed O.J. was guilty,” she added.

Caitlyn went on to speculate whether part of Robert’s motivation behind defending Simpson was to obtain some form of revenge against his ex-wifeKris Jenner, who was close friends with Brown Simpson.

“I wonder if it was his way of saying to [Kris] what I think she was saying to him when she married me: a big f— you,” she wrote.
